Barcroft Media's Year in Pictures 2013

A panoramic view of Mich Kemeter, 24, as he walks across a lake during a world record waterline in Tragoess, Austria. An adventurous climber has smashed a 'waterlining' world record - tiptoeing an incredible 820 feet along a slack line above a beautiful mirrored lake. Extreme sports champion Mich Kemeter, 25, walked the length of almost three football pitches to complete the energy-sapping challenge. It took the Austrian almost 20 attempts - and several falls - over 20 days to break his own record at the Green Lake in Tragoess, Austria.Picture: Mirja Geh / Barcroft Media
